also. By default, RIP direction is set to Both for the LAN and None for the WAN and the Version set to
RIP-1.

3.1.5 DHCP Configuration

DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows the individual clients
(workstations) to obtain the TCP/IP configuration at start-up from a server. You can configure the Prestige as
a DHCP Server, Relay or None. When configured as a Server, the Prestige provides the TCP/IP
configuration for the clients. If set to None, DHCP service will be disabled and you must have another
DHCP sever on your LAN, or else the workstation must be manually configured. The Prestige can now also
act as a surrogate DHCP server (Relay) where it relays IP address assignment from the actual real DHCP
server to the clients.
IP Pool Setup
The Prestige is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to 192.168.1.64.
This configuration leaves 31 IP addresses (excluding the Prestige itself) in the lower range for other server
machines, e.g., server for mail, FTP, telnet, web, etc., that you may have.
DNS Server Address
DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa,
e.g., the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important because
without it, you must know the IP address of a machine before you can access it.
There are two ways that an ISP disseminates the DNS server addresses. The first is for an ISP to tell a
customer the DNS server addresses, usually in the form of an information sheet, when you sign up. If your
ISP does give you the DNS server addresses, enter them in the DNS Server fields in DHCP Setup. The
second is to leave this field blank, i.e., 0.0.0.0 – in this case the Prestige acts as a DNS proxy.

3.1.6 IP Multicast

Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender – 1 recipient) or
Broadcast (1 sender – everybody on the network). Multicast is a third way to deliver IP packets to a group of
hosts on the network - not everybody.
